The impact of cochlear implantation on health-related quality of life in older adults, measured with the Health Utilities Index Mark 2 and Mark 3
Journal Contribution - Journal Article
Purpose To determine the usefulness of the Health Utilities Index (HUI) in older cochlear implant (CI) recipients, the primary aims were: (1) to assess health-related quality of life (HRQoL), measured with HUI, in older CI candidates while comparing with age- and gender-matched normal-hearing controls; (2) to compare HRQoL after CI with the pre-operative situation, using HUI and the Nijmegen cochlear implant questionnaire (NCIQ). The difference between pre- and postoperative speech intelligibility in noise (SPIN) and in quiet (SPIQ) and the influence of pre-operative vestibular function on HRQoL in CI users were also studied. Methods Twenty CI users aged 55 years and older with bilateral severe-to-profound postlingual sensorineural hearing loss and an age- and gender-matched normal-hearing control group were included. HRQoL was assessed with HUI Mark 2 (HUI2), HUI Mark 3 (HUI3) and NCIQ. The CI recipients were evaluated pre-operatively and 12 months postoperatively. Results HUI3 Hearing (p = 0.02), SPIQ (p < 0.001), SPIN (p < 0.001) and NCIQ (p = 0.001) scores improved significantly comparing pre- and postoperative measurements in the CI group. No significant improvement was found comparing pre- and postoperative HUI3 Multi-Attribute scores (p = 0.07). The HUI3 Multi-Attribute score after CI remained significantly worse (p < 0.001) than those of the control group. Vestibular loss was significantly related to a decrease in HUI3 Multi-Attribute (p = 0.037) and HUI3 Emotion (p = 0.021) scores. Conclusion The HUI is suitable to detect differences between normal-hearing controls and CI users, but might underestimate HRQoL changes after CI in CI users over 55.
